Good day folks. I'm having issues with my Century31 Autopilot. Keeps heading but up and down pitches with electrim "on". I took it down to Texas to a buddy of mine to look and see if the servos was faulty. Could not find any fualt. Also. The autopilot is not flying an approach. It pitch a 500' min down and capture a glidepath. Is there any buddy that has a spare unit that I can use to see if it the controller head. I know somewhere they said is to take it to the avionic shop where century factory is. Its not that easy for me to get there. I'm North of the border.
